> Does the cost include all updates to CC2 forever?
The license is for Construct 2 forever. Eventually (a couple years down the line) we'll come up with Construct 3. However, when we do that, we'll make sure there are some good upgrade deals for C2 users. This is the traditional software development model - it's likely we'll run out of money long-term unless we take this approach. We tried to suggest subscriptions to our userbase before but it was incredibly unpopular, so we'll have to go this way. Of course, there's plenty to do on Construct 2 first!
When does the Early cost end, if a date has been planned?
We haven't planned a date, but I guess it will be at least a couple of months.
Does the cost include all updates to Construct versions 3, 4, etc. forever, or will there be planned discounts for CC2 paid type people things?
As before there will be discounts, and everyone who has bought C2 within a certain time period of C3's release will get it free too. It's too far in the future to give specific details though.
Does any version of CC2 have an update feature, or are all updates at this moment manually to be downloaded? If manual, any update button for the future of the client?
Right now C2 has a simple update prompt - it tells you if a new version is available, but you have to download and install it yourself. We're planning to make this smoother in future.
What is the difference between scirra.com/construct2/releases/new and scirra.com/construct2/releases/r51.2 or are they both the same?
The /r51.2 URL always goes to release r51.2. The /new URL always goes to the newest release whatever it is. So when r52 is out, /r51.2 goes to r51.2, and /new goes to r52, etc. If you're copying and pasting the link it's best to use the /new one, since it keeps itself up to date.
